Abstract: A display panel with microcavities each having ends of asymmetric cross-sectional area. An exemplary display panel has a substrate; a pixel electrode formed on the substrate; a first black matrix and a second black matrix each disposed on the substrate; and a supporting member disposed on the substrate over the pixel electrode and the black matrix, the supporting member shaped so as to form a microcavity between the pixel electrode and the supporting member, the microcavity having an upper surface proximate to the supporting member and a lower surface opposite the upper surface. The microcavity has one end positioned over the first black matrix, and another end opposite the first end and positioned over the second black matrix; the lower surface of the microcavity has first and second channels disposed therein, the first channel positioned over the first black matrix, and the second channel positioned over the second black matrix.
